I've never had a chance to dive deeply into most 'advanced' math topics, but I've readd more than one of Hestenes's papers (and cohorts) and honestly GA looks to be so much clearer, concise, and more easily worked than having to blend together vectors, matrixes, and other constructs in order to do the same work in more complicated ways, with extra notational layers.

Again, I don't use any of this in real life, so YMMV, but it looks very clean, fast, and intuitive compared to (waves at everything else).
